In the operation of the cultivator, the driver may raise and lower themembers 62 and 63 by manipulating the lever 28, as will bc readilyunderstood, the raised position being illustrated in F 2 and the loweretposition being shown in Fig. l. By manipulation o'l the lever Q8, thedepth ot the ele ment 63 in the ground may also be regulated.

`When it is desired to cultivate under a tree which is in the way et thetractor, the angle iron 55 may be shifted laterally either to the rightor left by raising the cultivating members and turning the crank throughwhich the rack anl pinion are operated. The lateral movement ot thecultivating elements is illustrated in Fig. 3.

Thus it will be seen that have produced a cultivatng device comprising aframe rigidly secured to a tractor, an arcuate notched member secured tosaid trame, a second frame pivoted to the first trame and extendingrearwardly thereoi', a lever adjacent the drivers Seat of said tractor,said lever being secured to the second frame and adapted to raise andlower the second frame and to releasably engage said arcuate notchedmember, a third trame pivoted to the `first frame and resilientlyconnected to the second frame, cultivating members slidably secured tosaid third frame, a rack secured to said cultivating members, a pinionmounted on said third trame and engaging said rack, and a handle adaptedto turn said pinion to move said cultivating members.

During dry seasons or in arid regions, it is necessary to rely onirrigation, and in order to distribute water, small furrows or ditchesmust be dug, as is well understood.

lith the ordinary cultivating implements, turrowing blades or shovelsare substituted. for the harrowing blades by first removing theharrowing blades (usually about eleven in number) from the cross bar,and then fastening three iurrowing shovels on the same bar-usuallyconsuming about ltwo hours time. F rom the construction ot' my device,it will be seen that the angle iron or bar carrying the harrowing bladesGB is removable from its supporting member. 'lheretort-i, when it isnecessary to change from harrowing to furrowing, as mentioned above, thebar carrying the harrowing blades is removed and a similar bar carryingfurrowing blades is Ainserted in place thereof, which only requiresabout two or three mintites,` thus saving considerable time and labor.

the angle iron with the rack connei'ed thereto may be' slidlongitudinally to one side or the other and completely removed from thebar 54. A similar bar 55 with a similar plate 58 with a rack securedthereto may then be inserted on the end ot the bar 54, such bar 55carrying a different type of cultivator members 62 and 63. is soon asthe rack engages the pinion the pinion may be turned Ato draw the bar 55into proper position. it desired the plate 5S having the ruoli thereonmay be detached from one bar having a certain type of cultivator teethand attached to another bar having a. differenttype ot' cultivatorteeth. Thus l may readily replace one type of cultivator by substitutingthe whole bar 55 with a new rack or by changing the rack to another bar55 having different cultivators.

This invention has been described but modiiications thereof may bedevised without departing` from the spirit thereof, and it is to beunderstood that such modifications come within the scope ot thisinvention.

lV hat is claimed is l. An orchard cultivator comprising in combinationa tractor, a cultivator iframe connected to the tractor and having apair of supporting elements at its rear end, a readily removablecultivator comprising a transverse bar bolted to said supporting ele'ments, a slidable bar mounted on the transverse bar to slide lengthwisethereon, a rack connected to said slidable bar, cultivator elementsconnected to the slidable bar, a pinion supported by the cultivatortrame, meshing with the rack and manual means to operate thc saidpinion.
